I need help with this Java problem. Please use the provided code to test as well. Screenshots of this problem and the tests to run are below. I cannot provide screenshots for FractionMatrixTest.java because it is too long.

Problem:

public class FractionMatrix implements FractionMatrixI { /////////////////////////////// FIELDS /////////////////////////////// private Fraction[][] array; private static final Fraction ZERO = new Fraction(0); //////////////////////////// CONSTRUCTORS //////////////////////////// // Construct an m x n matrix with null elements. public FractionMatrix(int m, int n) { array = new Fraction[m][n]; // all elements are null } // Construct a matrix with dimension and elements copied from a. // Precondition: Array a is rectangular public FractionMatrix(Fraction[][] a) { int rows = a.length; int cols = a[0].length; array = new Fraction[rows][cols]; for (int row = 0; row
